Answer: Nemesia 'Aromatica Royal' grows 12-14 inches high, and 10-12 inches wide. It grows in full sun to part shade and blooms from spring until frost. It prefers moist, organic, well drained soil and appreciates a light feeding every two weeks. (I use a half-strength dilution of liquid fertilizer such as Miracle-Gro or Peter's). If you remove the spent flowers, the plant will look neat and tidy and will flower even more prolifically.
If your plant looks puny, it could be simply a sign of transplant stress. Watering it when the top of the soil begins to dry should help the roots become firmly established, which should help its overall appearance and productivity.
There are several types of campanula and the foliage looks different on each one so I don't think that is a symptom of a problem. Campanula will grow in full sun to part shade so the site sounds good for them. They will rebloom if you cut off the spent flowers (or the flowering stem). It takes a few weeks for rebloom.
Your delphinium will produce a single stalk of flowers; if you cut the stalk down when the flowers are spent, it may send up two smaller stalks and bloom later for you.
Plants that are not thriving, even when being regularly watered and fed, are usually reacting to the growing environment or even the soil. You may want to repot them in fresh potting soil and set them where they get morning sun and afternoon shade. Let's hope they perk up soon!
